ADJUSTABLE KNIFE-GAGE.

Speccaton of Letters Patent.

PatentedA March 12, 1907.

Application filed November 21, 1906. Serial No. 344.472.

To all whom it may concern.-

Be it known that I, EDWARD COLEMAN, a citizen of the United States,residing at Minneapolis, in the county of Hennepin and State ofMinnesota, have invented new and useful Improvements in AdjustableKnife-Gages, of which the following is a specification.

My invention relates to gage attachments for knives for cutting leatherand similar material; and its objects are to provide a simple andconvenient attachment that can readily be placed upon and removed fromthe knife-blade and which while in place may be adjusted for cuttingstrips or ribbons of desired widths; also, to adapt the gage for use asan attachment for ordinary pocket-knives that may be readily placed andremoved at pleasure.

My improvements are illustrated in the accompanying drawings, in which-Figure l is a side elevation of an attachment embodying the inventionand showing the same applied for use on a knife. Fig. 2 is a horizontalsection taken on the line 2 2 of Fig. l, and Fig. 3 is a verticaltransverse section taken on the line 3 3 of Fig. 2 and showing the partson a larger scale.

Referring to the drawings, 1 designates the cutting-tool, preferably anordinary pocketknife having a handle 2 and a folding blade 3, having asharpened cutting edge 4.

rIhe gage devices comprise a member having a body -portion 5, providedwith a pair of clamping-jaws 6, (preferably spring-jaws,) `joined attheir forward ends and preferably normally divergent from front to rear.Near their rear ends the jaws are provided with a thumb-screw 7 forclamping them to the blade 3. At the forward end of the body 5 is alaterally-projecting arm 8, provided with an elongated longitudinal slot9, in which is a slidable screw 10. This screw engages with and carriesa substantially L-shaped gagehead ll, which is provided with dependingside flanges 12, that bear on the adjacent edges of the arm 8.

In practice the gage-body is secured in place on the blade 3 by seating'the latter between the clamping-jaws with its edge 4 toward the frontend of the body 5, and the jaws are then operated by the screw 7 toclamp and hold the parts in place. The gagehead ll may then be adjustedalong the arm 8 in accordance with the width of the strips to be cut andsecured at the point of adjustment bymeans of the screw 10. When soarranged, the head l 1 is brought to contact with the edge of theleather or other material to be cut, and the knife is drawn toward theoperator to cut a strip or ribbon from the material, the blade movementbeing guided by the contact of the gage-head with the edge of thematerial.

It is obvious that the device can be readily removed from the blade byturning the screw 7 to open the jaws, and it is also obvious that thegage-head can be easily adjusted for cutting strips of different widths.

An especial advantage of this device is that it is adapted for use inconnection With a knife-blade of any style, thus enabling it to be usedas a removable attachment for an ordinary pocket-knife.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s-

l. A knife-gage, comprising a body p0rtion providing clamping-jawsadapted to engage a cutting-blade, an arm extending laterally therefromat a right angle and provided with a longitudinal slot, a gage-headadjustable lengthwise of said arm, and a screw operating in said slotfor holding the gage-head in place on the arm, substantially as setforth.

2. A knife-gage, comprising a body portion providing clamping-jawsadapted to engage a cutting-blade, an arm extending therefrom laterallyand at a right angle to the side of the blade, a flanged L-shapedgage-head slidable on said arm, and a screw operating in said slot forholding the gagehead in place on the arm, substantially as set forth.

In testimony whereof I afiix my signature in presence of two witnesses.

EDWARD COLEMAN.
